FL12RX FLASHLIGHT

LumaRay FL12RX Flashlight, retail $134.95 (www.lumaray.com...)
Manufactured by LumaRay (www.lumaray.com)
Last updated 03-02-12

The LumaRay FL12RX is a new LED flashlight that features eleven white LEDs and one red LED in the bezel, powered by three C cells in the barrel. It is named the FL12RX because it uses eleven super bright white Nichia NSPW500CS (the brightest Nichia model available as of 11-2006) LEDs and one super bright red LED.

It comes in an amost all-plastic body, which (as you will read below) appears to be made out of some pretty "tuph stuph".

The new FL12RX has five modes, which you'll read about a little farther down this web page.

SIZE

To use the FL12RX, feed it first (see directly below), and then you'll be ready to rock.

Mode 1: Twist the bezel (head) clockwise (as if tightening it) to turn the FL12RX on (lensed and unlensed white LEDs) in full power mode, and twist the bezel counterclockwise (as if loosening it) to turn the FL12RX off.

Mode 2: Twist the bezel clockwise again to turn the FL12RX on with only the unlensed white LEDs, and twist the bezel counterclockwise (as if loosening it) to turn the FL12RX off.

Mode 3: Twist the bezel clockwise again to turn the FL12RX on with only the red LED, and twist the bezel counterclockwise (as if loosening it) to turn the FL12RX off.

Mode 4: Twist the bezel clockwise again to turn the FL12RX on with only the lensed white LEDs, and twist the bezel counterclockwise to turn the FL12RX off.

Mode 5: Twist the bezel clockwise again to turn the FL12RX on in strobe mode, where the white LEDs and red LED alternately blink at ~3Hz (~3 cycles per second), and twist the bezel counterclockwise to turn the FL12RX off.

When the flashlight is turned off for more than three seconds, it will next come on in Mode 1 regardless of which mode it was last used in.

There is no momentary or signalling function available, so don't look for or expect to find one.

A greenish glow will come from the LEDs when the FL12RX is off and it had been used recently; this is from a GITD (Glow-In-The-Dark) compound around these LEDs, and if the flashlight is set where you can see the bezel, the glow should be visible with dark-adapted vision for up to ten hours.

I don't normally show flashlight packages, but this one is unique enough to warrant such a photograph. Note: This is the box a LumaRay FL12 comes in; that's why it reads "FL12" on the side.

To change the batteries in the FL12RX, locate the cantilever assembly below the bezel (head), and while holding the flashlight so the business-end faces the ceiling or sky, turn this cantilever assembly counterclockwise (as if loosening it) until it stops.

Hold the flashlight in one hand, with your thumb over one of the pads on this cantilever assembly. With the other hand, place your thumb and forefinger over the other two pads on the cantilever, and push down (toward the tailcap) on these pads. This should release the bezel.

Remove the bezel, gently place it on the ground, and kick it in the garden so the praying mantids will think it's something yummy to eat and strike at it...O WAIT!!! THAT'S THE GOOD PART!!! So just set it aside instead.

Tip the three used C cells out of the barrel and into your hand, and dispose of or recycle them as you see fit. Shake the flashlight slightly if necessary if the cells do not slide out. This is a feature of the FL12RX, so when you're changing batteries in total darkness, they won't just all tumble out and fall on your feet...ouch!!!

Drop three new C cells into the barrel, button-end (+) positive facing outward.

Press the bezel straight onto the barrel until you hear it click; then turn the cantilever assembly clockwise (as if tightening it) until it stops and you hear a clicking sound.
Aren't you glad you didn't kick that bezel into the garden with all those hungry, hungry praying mantids now?

Here is what a praying mantis looks like.
I found this guy on the morning of 09-08-06 clinging to the basket of my scooter.

Photograph of the bezel. That greenish glow you see coming from the LEDs in the bezel is a glow-in-the-dark compound in there; this is completely normal and is nothing whatsoever to be concerned about.

The FL12RX appears durable, and IS durable. When I administered that terrible smack test on it (ten whacks against the concrete floor of a patio; five against the side of the tail and five against the side of the bezel), only the expected damage was found: some *VERY* minor gouging on the bezel where it was struck; no damage of any type was found on the tail. No optical or electrical malfunctions were detected. I performed this test with the batteries loaded - nobody goes around throwing *EMPTY* flashlights.

Water-resistance is AAA+++.
The FL12RX is waterproof and submersible to 50 feet, so you need not be concerned about using it in foul weather; and water-landings won't kill it either. And if the dog takes a leak on it, just take the garden hose to it or douche it off under the faucet - good as new.

The FL12RX will stand on its tail to shine on the ceiling, so it can be used as a flameless "candle".

The barrel has a very lightly pebbly texture with a series of circular depressions moulded into it; both the tail and bezel have plenty of texture (in the forms of longitudinal ribbing and slightly projecting parts), so retention (the ability to hold the flashlight when your hands are cold, oily, gloved, or wet) should not be a major issue here.

The large flutes in the bezel (head) function quite well as an anti-roll device.

A lanyard may be attached if desired, use any of the attachment points on the tailcap for this purpose. A lanyard is not provided with the FL12RX; if you wish to use one with this flashlight, you'll have to procure it elsewhere.

The primary light output consists of a medium spot with a sharp fall-off at its perimeter, produced by convex (magnifying) lenses in front of the six LEDs around the outer perimeter. A corona outside the main beam is provided by the five unlensed white LEDs in the center. All of the individual beams from the outer edge of the bezel coalesce into a circular beam at approximately 8".

The FL12RX features a "soft start" routine, where the LEDs come on gradually (over a period of ~2 seconds); this is so you don't just become blinded by the light (no pun intended) when you switch the unit on. This behaviour covers the first four modes; it does not come into play when the unit is switched to strobe mode (mode #5).

Besides having substantially brighter LEDs, the length of the flashlight has been reduced by ~0.5" from the previous FL12 model, water-resistance (submersibility) has been increased from 15' to 50', and the barrel ("handle") has been redesigned.

*** VERY IMPORTANT!!! ***
Due of the redesign of the handle (barrel), the old head unit (from the earlier generation FL6 and FL12) will not fit on the new handle. However, the new head unit will work with the old handle style.
